MOP RINGE Application filed Decemberll, 1930; Serial to. 501,500.

This invention relates to mop wringers. Numerous attempts have been madetoprovide a satisfactory wringer which would meet the demandsrequirements of the public. 5 These attempts have encompassed severaltypes of wringers; one in which the mop is passed between squeezingrollers, another in whichJa mop is twisted, and the third in which wateris squeezed from the mop by 10 means of the application of pressure. @f

these three well known types the-lastmentioned is by far the inostBfiCii1lV85 by-areason of the fact that little 'or'no daniage istdonetothe mop by repeated squeezing operiati'ons.. 1

The general aim of the present invention is the provision of improvedmeansi-n the last named type of wringer for applying a squeezingpressure to twosides'of .the' wringer" by moving a plurality of opposedsplatesrtow-ard each other. 1 11+.

One obi'ect is the provision of amopiwringer which issimple'inconstruction;-clurable' in service; effective in operation, andinexpensive to manufacture. a i

The pins 30, which extend inwardly from the plates 28,cooperate with horizontally disposed slots 37 fashioned in cars 38formed on brackets 39. Slots 40 in the brackets 39 cooperate with thepins 35 andsimilar slots 41 cooperate with pins 42 anchored in the sidebracket 10 so as to guide the members 39 in their vertical movement. Thelower extremities of the members 39 are provided with arms which extendoutwardly and downwardly. Cam slots 43 are formed in the arms in such amanner as to encompass the pins 22 and 23 formed on the ends of theplates 19 and projected throughthe slots 24 and 25 in the end plates 10.I

' The bar 26 is provided with a handle socket 44 adapted to receive andretain a handle 45 in any provided manner. When the handle 45 is swungfrom the position shown in Fig. 3 to that shown in Fig. 4 the plates 28,carried by the end of the bar 26, are rotated and the pins 29 areswungrearwardly and upwardly while the pins 30 are swung forwardly anddownwardly. As previously described, the pins 29 and 30 cooperate withslots 31 and slots 27 respectively in the members 33 and members 39. Asthe pins 29 are drawn rearwardly and upwardly they impart movement tothe members 33, and in so doing raise the bottom member 15-of the mopbasket. Simultaneously with this motion the'pins 30, which are acting inthe slots 37, move the members 39 downwardly and in so doing impart tothe pins 22 an inward movement along the horizontally disposed portionof the slots 43 and the downwardly inclined portion of the slots 24. Asthe members 39 start their downward movement'the pins 23'remain in thehorizontally disposed upper ends of the slots 25 until such time as theextremities of the pins 23 engage the horizontal portion of the slot'43. At this time the follower plates l9 have reached a substantiallyhorizontal position. Continued pressure will force the plates 19downwardly in opposition to the upwardmovement of the member 15. It willthus be noted that a'mop which has been positioned within the receptaclewill be exposed to pressure of the plates 19 and member'15simultaneously and by reason of this quickly and forcibly e ectedfrom'the'mop.

When the mop has been exposed to sufii- 'cient pressure to free it ofall excess water,

the handle 45 may be swung back to the posiwater by the simple and easymanipulation of handle45. The construction of the wringer is such thatready application and removal of the wringer is possible by reason ofthe fact that the interior of the mop receiver isfree from moving parts.The several guide and cam slots formed in the end plates of the wringerserve to permit the application of the, actuating means to the outerwalls of the plates in a manner which facilitates their'free andunimpaired movement. By virtue of the fact that all of the actuatingmeans are mounted on the end plates, itis possible to provide a smalland compact device of unusual strength and durability.

Various changes may be made in the embodiment of the inventionhereinabove specifically described without departing from or sacrificingany of the advantages of the invention as defined in the appendedclaims.
